Revolutionary Committee of the Chinese Kuomintang

The Revolutionary Committee of the Chinese Kuomintang (RCCK) is a democratic socialist political party in China which was founded on 1 January 1948 by Sun Yat-sen's widow Soong Ching-ling and other leftist former members of the Kuomintang party. The RCCK was formed after Chiang Kai-shek betrayed his alliance with the Communist Party of China and purged left-wing members of the party, turning the KMT into a conservative and authoritarian party and forcing its democratic socialist and social democratic members to form their own party. The RCCK allied itself with the CPC and became the second-largest political party in mainland China; by 2017, it had 131,410 members and ran its own party schools.
